Glycol concentration for make up air units
Glycol concentration for make up air units
(OP)
I currently have a project which recoverys heat from condensers to preheat make-up air. My question is how much glycol concentration is proper for make-up air roof top unit? my concenption is that even at night the unit is shutdown, the water loop still keep on runing, therefor, it is not necessary to put the water solution freezing point lower than winter design temperature which would result in high concentration on the water loop system. Thanks for opinions and recommendations

If you your max temp is less than 250 F use SR-1. Pick your min. OA temp. h
